TOFO - I think we were very 'special'
Around the time of the last downbanding, I think there were a few AEOPs in other fleets who were very glad of the 'specialness' of the kipper cadre. I remember the amount of time and energy spent by many (especially the MACr and AEOs) building a case to prove the 'specialness' of the WSOp trade. All ancient history now.
Re the Officer vs SNCO debate, some individuals could fill the roles, some maybe not. I think the more salient point for P8 will be the number of soon to be 'seat-less' ex-GR4 (and other fleet) Nav/WSOs. Why use a SNCO WSOp (who you will need to fill another seat) when you have a spare bod already?
I'm not sure this 'recruiting' drive is as widespread as indicated. Maybe a few specific individuals for specific skills?
